David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

David Turner 4eee13404d Remove Jamfile files from the tree.
These have not been used in a very, very long time, so better remove
them.  A corresponding patch will be submitted to the
`freetype2-demos' repository.

Werner Lemberg bd75a517dc [type42] Fix glyph access.
This is a severe bug: We've missed one level of indirection, as
described in the Type 42 specification.  As a result, ftview
sometimes showed incorrect glyphs for given glyph names, and even
displayed `error 0x0006' (invalid argument!) in case the number of
glyph indices differed between the Type 42 font and the embedded
TTF.

Apparently, noone ever noticed it; this shows how much Type 42 fonts
are in use...

to embedded TTF's glyph index.
